Last week, I posted a brief blurb about a package I received in the mail from “J,” a man with an unwholesome fixation with barn swallows. In that relatively innocuous package, J sent over a Sony IC Reader pre-loaded with 18 seconds of birds chirping. While I did not know it at the time, the package was the entryway into a secretive, five-part application process for Her Majesty’s Secret Service, MI6. The campaign, developed on behalf of Sony by Wieden+Kennedy, revels in secrecy through every step of the design process. As such, unlike many alternate reality games, much of the thrill in this experience can be derived from tackling the challenges on your own.
